I decided to take you up on the challenge and Googled some of the names. Of course, the first step was to look up the imdb page to see what's there.

Francine Lassman changed her name to Abbe Lane and married Xavier Cugat. She made a few movies and did a lot of television work. She said, "Jayne Mansfield may turn boys into men, but I take them from there"

Bob Hastings had a very long career in television and continues to do voice over work.

People for whom this is the only screen appearance listed in IMDB
Albert Adams, Kingsley Colton, Bernard Daly, Jean Hemond, Francis Lacey, Richard Monahan (did 1 other short), Michael Bell Ensemble, The Morgenwecks
There's a start. Maybe some others will enjoy looking up more names.
3 stars for average production values, concept, etc. An extra star for charm.
